Yeah I know Apex and Nova are more popular, but for some reason I prefer Holo.

It might the fact that it allows me to use the home button to launch the regular bottom screen Android menu.
As the non-rooted HTC Ones dont allow that, for some reason - but the next Sense update will fix that.

Oh Im also enjoying Holo Locker (Nexus locker)

Holo Locker is awesome. I've been using it for some time. It's even better with the notifier add-on.

I've yet to get with the times. I've been using ADW.EX launcher for years now. It does everything I need and I'm used to it. I've never had any reason to try something different.
